Abstract

A condensing zone for pneumatic condensing of the drafted, still twist-free fiber strand is arranged downstream of the drafting apparatus of a ring spinning machine. The condensing zone is limited by a delivery roller pair, whose driven bottom roller is a suction roller, which is arranged directly downstream of the front roller pair of the drafting apparatus. The fiber strand loops the suction roller at an angle of at least 45.degree..
